This talk is titled "GNU poke, the free extensible editor for structured binary data," and was presented at LibrePlanet 2022 by José Marchesi.

José is a GNU hacker and maintainer. He is currently employed by Oracle as the Tech Lead of their toolchain/compilers team.

This talk is about GNU poke, which is an interactive editor for binary data. Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them. José will discuss these features and more.
